I have just replaced the old rubber brake lines with HEL stainless lines, and found a little problem in the process. Without the lines connected to the calipers, brake fluid runs out constantly without the brake lever pulled in. Makes it easy to bleed the air out, but doesn't seem right to me? I'm thinking the brake master cylinder needs a kit put through it. Does anyone know the Brembo part number of the kit? Or failing that, the Ducati part number?

I'm also thinking a radial brake master might be a reasonable upgrade, with a remote reservoir. Has anyone taken the plunge and fitted one?

The fluid should run straight thru as you describe Nick . With the piston assy at the normal resting position the port from the resiviour to the cylinder should be open and the fluid will flow , if you pull the lever in a bit ( thus closing that port ) the flow should stop. Im pretty sure I have the correct Brembo kit somewhere so I will look it out and get the part # off it for you . Those kits are also available from MG's , just need to know the diameter. Some of the whole master cylinder assys are cheap enough to just put a whole new one on there Hamish

It seemed a bit odd the fluid ran through. I did look at a few master cylinders on eBay. The you beaut, straight from China are beer money, but quality could be an issue? I have a British Princess sitting next to the 907 and it has a radial brake master (hence the second question). I thought the 907 had reasonable brakes, but you don't realise how much brakes have evolved until you take the Ducati for a run, and then jump on the other. Savage is a word that come to mind.

The 907's brakes are better with the HEL brakes lines, but still a little to go. It has been having a rest for about 12 months, so all the little rubber bits have dried out. The first time I went out on it after replacing the lines, one of the fork seals started leaking big time. Everything on the LHS is drenched in oil. So that is next, new brake pads and see what happens.

On mine, I had a couple of scares i.e. lever touching the handlebar trying to stop at a traffic light; at the time I though the issue was with the fluid so I replaced it and after bleeding it several times I decided the MCs where crap and replaced them with the Serie Oro from a 916.

Some purists will say "I ruined the bike's Originality", but I believe it is a mod that could have been made at the time of the bike production, therefore... yes, it is not original, but is not out of place.

With the serie oro the bike brakes as it should, looks nice and feels very nice.

Of course I also replaced the calipers, Serie oro all the way.

Yep, this is exactly what I would like to fit to the 907.

Some would say you may have ruined the bikes originality, but when you are planted in the front of someone's bonnet 'cause you couldn't stop doesn't do a whole lot for originality either!

New or 2nd hand Nick ? Im pretty sure I still have the clutch side .... and there was no issue fitting it over the choke ( Im assuming that's what Gert means by idle lever ) as the SS had the same handle switch assy as the Paso . Apart from looking a bit more "tech " ( gold , remote rez and adjustable has got to be hard to beat ) than the standard ones I couldn't see them making any real difference ..... as long as the overall pump/lever ratios were the same
